CO Depletion in Infrared Dark Clouds
G. Cosentino, J. C. Tan, C. Gainey +10
Infrared Dark Clouds (IRDCs) are cold, dense structures representative of the initial conditions of star formation. Many studies of IRDCs employ CO to investigate cloud dynamics. H…
Shocked Molecular Hydrogen and Broad CO lines from the Interacting Supernova Remnant HB 3
J. Rho, T. H. Jarrett, L. N. Tram +6
We present the detections of shocked molecular hydrogen (H2) gas in near- and mid-infrared and broad CO in millimeter from the mixed-morphology supernova remnant (SNR) HB~3 (G132.7…
Construction of Compactly Supported Shearlet Frames
P. Kittipoom, G. Kutyniok, W. Lim
Shearlet tight frames have been extensively studied during the last years due to their optimal approximation properties of cartoon-like images and their unified treatment of the co…
Compactly Supported Shearlets are Optimally Sparse
G. Kutyniok, W. Lim
Cartoon-like images, i.e., C^2 functions which are smooth apart from a C^2 discontinuity curve, have by now become a standard model for measuring sparse (non-linear) approximation…
Irregular Shearlet Frames: Geometry and Approximation Properties
P. Kittipoom, G. Kutyniok, W. Lim
Recently, shearlet systems were introduced as a means to derive efficient encoding methodologies for anisotropic features in 2-dimensional data with a unified treatment of the cont…
Mother of Dragons: A Massive, quiescent core in the dragon cloud (IRDC G028.37+00.07)
A. T. Barnes, J. Liu, Q. Zhang +15
Context: Core accretion models of massive star formation require the existence of massive, starless cores within molecular clouds. Yet, only a small number of candidates for such t…
